I .Distributer.

limit at 5 which is the center of convergence and distribution.

Figs. 3 and 4 show separately details of construction of a distributing .il'e carrier.

.A thin and strong carrier 6, is held in the grooves of the distributor by the arcs 3, 4; it is provided at the bottoin with a piece of sheet metal bent and riveted on to the oar-' rier forming a guide ier. tho passage of the brings back the carrier as soon as the jacquard' has ceased its pull.

Fig. 5 is a complete view of the distributer, its gripper and its shears. The gripper is supported upon a bar shown. separately at Figs. 6 and 7, which rocks upon pivots 13, 14:, the oscillation being regulated to the length of the pile thread by a cam and lever acting upon the pin 15. The gripper opens or closes under the action of a slotted lever having a rocking-center 1.6 and driven by a cam and a lever extending to the pin 17; then in the same slot, a pin 19 acts through the rods 19, 20, 19, 2-1 on the arms of the gripperfor seizing the pile thread brought by the carriers to center of distribution 5.

shears and oscillating at 22 is actuated at 26 by a cam so as to bring the shears near to the center 5 to there cut the pile thread at the required moment. This displacement has for object to give free assage to the ends of the pile thread exten ing beyond the carriers and also to allow the gripper to freely come and seize them but is not indispensable in all cases.

In certain stitches which. will be referred to the distribution is effected through loops in the warp either by a guide, the end of which is bent back and extended (Fig. 8) or by a tubular guide (Fig. 9) mounted on the distributer rocking upon pivots 27, 28 (Fig.

10). In the latter case (where the distribu ter is arranged to rock) the arms of the gripper have only one movement, that which permits the seizing and holding tight of the pile thread, and the rocking movement upon the pivots 13-14 (Fig. 5) is suppressed.

It will be seen from Fig. 8 and from the further description hereinafter that the pile thread can be seized by the looper on one side or the other of the gripper. is applied according to the length of the pile thread to be used.

H. Lifting and Wagi of Acting of the Two Warp Threads. Each war thread is actuated by a heald which is tig-itened to the hook of a special jac uard mechanism. The latter is actuate by the knotting system. These healds.

are fixed to rods which are connected with the Weaving loom, so that each war thread may be at first lifted by the jacquar for the The shears,,- mounted upon an arm pivoted at ZZfhaveblade fixed and formed withf'a.

This detail tying of the knot; then all the warp threads may be lifted by the weaving heddles for the weaving. The two warp threads on which the knot stitch haste be produced are not only lifted, but they help to the formation of the knot by their different positions to which they are brought. These successive positions constitute the whole work of the warp threads, and they may be thus explained; They are (1) lifted; (2) separated from each other (3) divided to allow the passage between them of the loopin grippers; (4c) lifted by the looper close to t 1e pile thread of the distributer; (5) then brought towards their natural position and distance apart for the tightening of the knot; (6.) then strained for the sliding, the putting in place and the locking of the stitch; and (7) at last lowered to the position of the other warp threads. Figs. 11, 12 and 13 show the details of con struction for the raising of one warp thread. A hook 34 lifts successively one after another the bifurcated healds 40, 41. These healds thus roduce the lifting of the two Warp threa s 185, 185. This mechanism may be adopted instead of a specialjacquard for the lifting of the war threads.

A row of loope healds'or leashes is placed throughout the width of the warp; the number of these healds is equal to the dents of the reeds and half that of the warp threads. They can be actuated directly bya jacquard or each suspended from a book all together constituting with the row of hooks a jacquard mechanism of the width of the warp and the inverted hook of which being laterally displaced to successively lift hook by hook produces the same effect as the needles 7 and cards of the jacquard. The object of these healds is to successlvely lift together the two wa p threads which are entered in, each loop aid on which the knot should be set and which on passing through the reed are separated by a dent. This loop issuiliciently high to allow the crossing oi the two war threads to take place under the action of t e heddles of the weaving loom and in which they are entered thread by thread;

reciprocally, the 100 s can raise the two threadsby reason 0' the peculiarity mentioned of the leashes, as the latter are not connected at their u per parts and have leads suspended from t eir leashes or threads. These arrangements therefore allow alternately either the action of the healds with loops for raising two war threads, or the action of the weaving held ice on all the warp threads at once :for'weavin'g. Many'other arrangements couldbe employed without in any way alterin the process of se di ating the twowarp tn'eads on which tiehnot stitch is produced.

- Fig. 12 shows the hook 31 which is an inverted hooir adapted to lift the other hooks; the shaft 29 which receives its movement of the knot-stitch. This from a cam and lever transmits by the levers 29, 30 and 30, 31 the lifting and lowering movements to the hook mounted on the guide rod 32, 33 the hook 34 is liited to its extreme limit; its downward motion is limited by the shoulder .35 abutting upon the guide bracket 36 which, with the guide bracket 37 directs the course vertically; dvisions are made in these guides to keep the hooks at equal distances a art as shown in the plan view of the row of ooks, Fig. 13.

' Figs. 11 and 12 show the batten 38 and the strips 39 'of the weaving loom; the raised loops 40 and the lowered loops 41, and the leads 42 of the healds.

I]I.-Divider and Tightens) of the ii arp Threads.

The divider and tightener of two warp threads has for object to separate themfor the assage of the looping grippers which will e hereinafter described and to tighten them for the locking and )lacing in osition divider is s iown in front and side view at Fig. 14. This apparatus is fixed on the shaft 43 which moves it in its alternate rocking movements obtained by cam and lever the piece attached to it serves at the same time as a bearing for its pivot 44. The crank 45 imparts to it movement of rotation of a quarter of a revolution by means of a rod acting upon the pin 46 and driven bycam and lover. The front view shows'at its lower end and in its axis an anthe two warp threads.

gular notch 50 wherein the two warp threads are shown in section. This the position they occupy for their tension. The side elevation shows at this'same end a point 47 slightly rounded and also, in section, the two warp threads. This is the position for offooting their separation.

' In Fig. 15 the divider and tightencr is supposed to be lowered, its point t? is brought towards the dent of the reed which separates The latte are about to be lifted and passon each side of the point ii", the shaft 43 slightly lifts the divider, its crank causes it to make a quarter of revolution and .the whole stops, Flyv l6.

. By reason of the shape of the divider, the two threads are not only divided but strained and retained by the shoulders 48. 49, Fig. l4;

this is the position which allows the looping grippers to pass hetween the threads in order afterwardsto turn round thenrto take up the pile thread which is at this moment distrib- .uteda.and held. in tension between the distributor. and its gripper. As soon asit ized-hy the loopingdcvicc it is out by the shears, released b v. thc gripper taken up and drawn'along; At the same time, the divider andtightonerislowered and turnedhack its quarter of a revolution, raised i norder to disengageitlrom the two warp threads, turned back its-quarter ofa revolution, and lowered on to them to arrive and take the almost vertical position shown in dotted lines in Fig. 17. As the Warp threads are then brought to wards their natural position and distance apart they become united in the angle 50 of the divider and tightener (Fig. 17); the ten.-

sion is so much greater as the lift of the heald loop is still maintained which offers for the sliding the putting in place and the locking of the stitch, the best advantages for execution. Theslitch being completed the divider and. tightener slightly rises comes back its quarter of a revolution, the hook and its heald fall, the lateral advance of the system is efiected, the divider and tightener resumes its first position, Fig. 15, but its point is now over the adjacent dent of the reed and so on. In certain divisions of the reed in order to further insure the concordance of the dent of the reed and the point 47 a small notch or slot 50 can be made in the divider and tightencr as shown in the section at Fig. 14 which fits over the said dent'SO Other mechanical arrangements would answer the purposes of the described apparatus; it' could also be separated into two apparatus the tightener and the divider and this arrangement would in no way alter the process which is; (1) to sufliciently divide, as required upon the movement of the reed, the two warp threads for the passage oi the looping grippers; (2) to strain the two threads to permit the sliding and the perfect forming ithe knot.

4. Looping Device.

In principle it consists of two grippers which serve to seize the pile thread it is distributed and not to leave it until after the placing and final locking of the stitch whatever kind of knot may be made. But as the different knot-stitches result from'the path lollowed by the ends of the two grip crs carryins along the pile thread in com ination with the warp threads, it is possible to obtain them by causing these ends to perform rotary movements or rectilinear movements; these ar c unimportant details of the mechanism butgc'annotbe ignored as they are capable of furnishing the some results. They are explained by the three following examples; (a) Looping device with grippers having rotary movements. (1)) Looping device with grippershaving rectilinear movements. (0)

-Mixed ldoplng device, that is to say, arising from the two others.

(a) Lpoping device hc'wing grippers with T0- zary mo'i emen-tsr Fig. 19 is a plan view of it and Fig. 20 is a side view. sisls of two tubes 51, 52 of equal diameter and parallel, passing through guides 53, 54. They work together in their alternate rotary movements through the medium of two pinions55, 56 keyed on the tubes; the pinions gear together and are driven by the sector 57 This device conrocking upon its .pi'vots 5859 and receiving its movement on the pain (Kl-through a cam and lever. (The para elism of the tubes is not an essentialquestion, because for making tial at the end 66in order to allow ofemp tary movement but the slots 64,- 65 allow the longitudinal movement which'corresponds to the opening and closing of the grippers, which are formed b the meeting of the two outer and inner tu es according to the arrangements shown at 66; moreover they are slotted or notched in order to effect the assage of the warp threads shown at 172. he inner tubes are formed integrally at '67 with the screw-threaded rods 67, 68 which pass over the brackets of the trunnions 73, 7 4, the

sockets 69, .70 of which with rings serve as sto s for the springs 71 and nuts 72. The iod and the inner tubes therefore have the same rotary movement and are actuated longitudinally by 'the cross iece 7-3', 74 which receives its movement tiirough connecting.

. rods 75, 76, actuated by the crank 79 of the shaft 77, 78 which carries at the end the crank 78, 81 forming part of the bell-crank I 81, 82, 85. The pin 81 is driven by the connecting r0d 81, 'actuated by t e double lever 80, 83 receiving at 83 the motion of a lever and cam. The s rings 71 placed on the screw-threaded ro s 67, -68 regulate, through the nuts 84 and 72, the energetic and equal grip of each of the grippers. 'The grippers have their maximum grl when the cens ters 76, 77, 75 are in a straig tline, which is subjected to a slight movement past the same below the. center, Fig. 21, inorder to insure, the grippers being held closed, the closure being regulated by the screw placed at 85 Figs.;19 and 2.0, whichunder the action-- of the spring 86 bears u on the inclinedplane'87. The spring 86'is -ed to the top of the piece 96, 96 and is there adjustable. All these pieces are held in the frame 91, 53, 54, 92 suspended above the pile of the carpet by the two shaftsi93which are themselves connected to arockin 'leve'aactuated by a cam;

The two rocking movements of the looping grip ers are thus insured and their action com ines with that of the other apparatus already described: (1) Fig. 22, they enter between the two warp threads lifted by the g they seize the pile thread bl'oughirl')- theifi-t andadjustable at 98 on the fixe part of the I The opening of the g P healds with bifurcations. or 1 and held by the divider and tighten en Fig. 23, they pass round them",-(3) Fi 24;

In these movements and in, I

these courses the ends of the tv'togrip'liiers have followed, through their doub1e-?e sc1lla tion, all the upward and downward evoluf-i'sda. tions of the two warp threads. 1-.

It is at'the moment of meeting of the withthe wefting'line'of the weaverthat' the I automatic locking is produced. The braclE- 'ets 61, 62 and the shaft 77, 78 (Figs. 19- a d ts 20). are connected by rods orv bars 94, 95.1

The ends of the brackets 61, 62 and the shaft- 77, 78 slide infthe slots 96 and 97 and are}. held at the bottom of their travel by the spring 98, 99 fixed at 99 to theiece 96, 96- v frame under the resisting action of the knot being tightened the two grippers firmly. grip? ping the (pile thread by each ofgits ends are there hel the frame'continues its'back'ward; 92 movement but the retaining force becoming greater than the resistance of the spring 98,- 99, the tubes slide in the guides 53, 54. drawingalong the piece 96, 96, thebars 94, 95, the shaft 77 7 8 arid consequently thebell- 16f) crank 81, 82, 85 and an adjusting s'crevrl' placed at 85, the end of the latter meetsthe inclined plane which, raising it, prevents-the slight movement beyond the stra' ht line shown at Fig. 21 which insures the c osing of the two grippers; immediatelythe tens on of' the spring 86 acts by rocking on the crank 79 and suddenly and automatically efiectstheir opening through the connecting rods 75, 76 acting upon the brackets of the shafts'73, 74.

At the. same time the grippers come back to their fixed position where-they were first de: scribed, under the action of the splring98, '99:

Q her automatic ora positive .mechanical means-"can be employed -lor apening the twdgrippers-but automaticfmeans are referable by reason of the regularity olitaine ai1d also; because they allow of treating as no ligible I the differences which may be produce in the l wefting line of the carpet, the variations of 12.5

positions of which may be somewhat appreciative. .It is therefore preferable to act automaticall as indicated by the arrangement which has been described as an example.

In the-last description is related that great avoiding the ravelingpf the the I side elevation.

ceives its motion by matic movement, the same closing and openlng arrangement, similar arrangements of obtained by the two looping grippers are actuated by two pin- I ions 55, 56, which gear together and are driven by a sector 57] These two grippers I thus work together under the action ofthe said sector in, order to produce the oriental knot-stitch, as explained for Figs. 22, 23, 24 and 25; but in order to obtain the Persian knot-stitch (Figs. 28 and 29) the two looping grippers have to work quite separately; therefore the two pinions have only to be slightly displaced sidcwise, so that they do not gear together. Each of these pinions rea special sector, each of these sectors being actuated by special cam and lever. By these means it is easy to un derstand that all movements or stops may be obtained for each gripper, as desired, in order to produce all sorts of stitches; oriental, Persian, wound stitches, and even for pile, threads distributed and brought to the weft ing line, in order to maintain it, by weaving in a ground texture.

(b) Looping device with grippers having rectilinear movements.The two grippersof this device com rise the same frame as that before describe they have the same autotheir ends and also of the slots or notches for the passage of thewarp threads; the same looping result as above is obtained. Only, as shown in Fig., 6, in place of the tubes sliding one within the other, flat bars or strips 99, 102 and 104, 100 are employed sliding one alongside the other in guides 105, 106, and which form at their end the grippers 100, 102. The bars or strips 99, 1112 rock upon their pivot 99 in order to allow the ends of the grippers to approach or move away from each other; this movement is obtained by the links 111, 109 actuated by the rod 111 112 and the double lever 112, 116, 115. The pin 115 is actuated by a cam. The opening and closing movements of the grippers are mechanical arrangements before described and which are connected at 104. The looping is effected in the same order explained for the rotary looping grippers: (1) They enter, adj aeent to one another, bc tween the two warp threads; (2) they separate below, rise and force the warp threads to take their position in their slots or notches; (3) they seize the pile thread; (4) thcy per form their return movement, draw along and lock the stitch at the wefting line V. Complete Zoom.

These frames are extended in heightand are V and in which they turn (shown onlF connected by the cross bars 123, 124-125, 126 serving as ways or rails for the carriage designated by the four rollers 127, 128, 129, 131) and on which are fixed the frames of the independent mechanism 131-132,133134, 135-136 which it draws along in its lateral movement. These frames support all the apparatus-of the independent mechanism with the cams, the shafts and the levers; the looping device fixed to its shafts 93,.withits supports 137, 13S, 139140 which oscillate upon the suspension shaft 139, 141; the distributer 1, 2, 3, 4, a carrier Lowered at 5, its gripper actuated at 21),21, its shears 23, 24 (not shown in Fig. 30); the. divider and t-ightener 47 and its operating shaft 43 (the means for setting the distributer are also not shown, the latter being held like the'gripper and theshears on the frame 135, 136). All

these apparatus are now illustrated wherein the distribution of the pile thread is effected, the looping grippers slightly lift the two warp threads in order'to afterwards seize the pile thread and loop it. At the upper part is shown the jacquard which actuates the carriersof the distributer rolling with its rollers 142143 upon therails 144145 which'are supported by (frames not shown in Fig. 31). The jacquard is connected to the independent mechanism for its lateral movement by the foot the frames of the weaving loom 146 fixedto the frame 135, 136. The hook is shown at 31, its guide at 32, 33, the row of hooks at 3 the healds with loops at 40. Finally the driving shafts 149 .and 150 on which are fixed all the cams driving the different movements of the apparatus, the shaftslSS,156,159,157,161)-151,161-153, 162 151, 163-155, etc. serving as attachments and gear to the levers transmitting the movements of the cams.

means of a pinion and shaft not'shown the motion of the transmission gear which from that time is given to all the system. These shafts 149 and 151) are round and are joined at 166 to square shafts 167. The toothed wheels 165 are adjusted to slide freely u on these squares, but are supported. by t eir sockets passing through two frames 107107 in the front view Fig. 30) which are-fixer on the ways 124 and 126 so that the square shafts turn with the toothed wheels and slide in their socket. A screw 170 fixed on the carriage by the piecc171 efi'ccts the lateral movement of the carriage and consequently that screw (not shown) which eilec-ts the motion of the carriage in both d1rect1ons.

VIZ. Multiplicity. of Systems.

The part comprised between the frames 1 3 1 132, 133, 134,Fig. is the head of the independent mechanism in that it incloses,

lows that in. the width of a loom the number i of distribution and locking members can be looping device with repeated such number being only limited by the space available.

The described mechanism with its arrangements and members products all the stitches which have been indicated and it will be well to revert to them in ordento describe their formations.

Knots tied by wcaotng.-Figs. 41, 42, 43, 44, 45 and 46.- The distribution is eiiected' in the lift of one or more warp threads, the grippers have only to seize the pilethread and up to the crossings of the warp threads which crossings it embraces and is hold therein. These crossings are. all that are required for obtaining a more or less firm hold of the knot.

In this description the combination of the whole of system is explained; but it is obvious that in certain cases certain parts of the above the loop gripper. grippers having rotary' movements, Figs. 22, 23, 24 25 and also that threads together and draws-them tight to to close asrequired, to draw it whole arrangement can be modified. Moreover this manufacture and the apparatus which has been combined for carrying it out allow of obtaining carpets with different knots oriental, Persian, or held by crossings or suitable arrangements arising from the warps and weaving. Also carpets of all kinds can be manufactured reproducing jdesigns of diilerent kinds in various colors with al pure or mixed textiles. i i

The described mechanisms may be a'dapted to weaving looms with vertical warps instead of with the horizontal warps shown. The relative movements of the parts in'the manipulation of the warp threads and the forming and drawing of the loo or knot,' will be understood most clearly ii'om reference to Figs. 46 00.53, or Figs. 54 to 61.

In the first position the divider and ti htener 44has entered between and slightly separated the lifted warp threads 172. The loopgripper 66 rests above the'warp threads. The pile yarn carrier 6, 7 is moved to the operating center and the end of the pile yarn is gripped by the grippers and so held in the second position the dividerand tightener 44 has lifted the warp threads 172 so that the looper 66lies below them, the other parts being approximately in 'l a same positions as before.

In the next position the two grippers of the looper have rotated in opposite directions, and the end of the looper has been raised, carrying with it the warp threads.

In the next position the same movement has continued until the gripping jaws of the looper have taken hold of the pile yarn 173, i the shears being operated to cut oil the necessary length. In the following osition the gripper 175 has released the pie yarn, the carrier 6, 7 has returned to its original position, the loop grippers 66 are in the act of returning to their starting position, and so also is the dividerand tightener 44.

.In the next position the loop grippers pull the ends of the knot up through the warp at i the same time that the divider and tightener 44 rises clear of the warp.

In the next position the looper still gripping the ends of the loop draws. the latter along the warp to the wetting line, the divider and tightener 44 being turned and pressed down so that its'notch holds the two warp permit the free sliding of the loop.

In the next position the loop 1sshown in final position, and all the parts ready to V commence a new operation.
